Like i have to say for this to work it would have to be connected to a Powder (E.G. BMLT) and if the bmlt is broken off or gone then the structure would fall and break. i know it would be VERY hard to code but an idea is a idea
another example of why we need a tutorial, but lolcats i cant blame you, nobody really explains why there cant be movable solids, so i will:
with the current programming language that TPT uses, any moving particle larger than 1 px would be impossible, somebody has tried and ended up with a bouncy powder. There is no conceivable way to create a moveable solid, and even with more cpu it is impossible, it would involve changing the entire source code.
This is hardly impossible, just no one who devs the powder toy at the moment has the math skills to just whip up all the code required.
Not really feasible at the moment, though Cracker came very close with the element EQVE. It used too much CPU checking for collision though so, doesn't really work in a typical sense like with particles.
